Thank you everyone!! I'm going to try the regumate this month and see how she is at our next show. I'm taking her up to Carson City, NV on October 8th for a horse show. It will be at the end of her heat cycle, so this will be good test.
When she get's ready to blow, it's like sitting on a 55 gal. drumb of TNT.
During our Pleasure class she was rearing up in the line up after the class, luckily she didn't do her usual big rear. Straight up and down, with no curve in her back. I probably would have slid out of the back of my pleasure saddle. I guess I could of landed on my feet, raised my arms in the air and said, "Ta Da!!" and bowed. Believe it or not she took a second with that performance. The judge must have completed her judging before Dandy began pulling her baloney.
During the trail competition she went completely bonkers and I had to dismount and walk out. Man I could have strangled her.
